For a powertrain or ADAS ECU that streams larger diagnostic or calibration blocks, the higher throughput reduces bus loading and frees bandwidth for other nodes. The 1/1 driver/receiver count is the standard single-node interface; you get one CAN TX and one CAN RX pair per transceiver. ## Supply rail and cold-crank margin The 4.5V minimum supply covers the typical automotive 5V rail during battery cranking, when the regulated bus can dip below 5V. As long as the local 5V regulator holds above 4.5V, the transceiver stays in spec — no brownout or bus-off glitch. The 5.5V maximum gives headroom for load-dump transients that the upstream TVS clamp handles.","metaTitle":"TCAN1042GDRQ1 CAN FD Transceiver, 5 Mbps, AEC-Q100, 8-SOIC","metaDescription":"TI TCAN1042GDRQ1 CAN FD transceiver, 5 Mbps data rate, AEC-Q100 qualified, -55°C to 125°C, 8-SOIC.
